Influence of partial serotiny of Aleppo pine, Italian, and Arizona cypress on seed germination

The usability of seeds for the production of seedlings, as well as the utilisation potential of seeds for natural regeneration was assessed by the comparative analysis of seed germination from the cones of different ages of three species with partial serotiny (P. halepensis Mill., Cupressus sempervirens L., Cupressus arizonica Greene). In cypress, serotiny is not so expressed as to be a reserve for extraordinary situations (fire). Fouryearold Aleppo pine cones should be collected for production purposes. Serotinous cones up to ten years old are efficient for natural regeneration of Aleppo pine forest after fire
